  1. Backport: Add _retry_server_directed_only mode for Retry-After header… 

    … compliance (#757)

* Add _retry_server_directed_only mode for Retry-After header compliance

When enabled, the connector only retries on 429/503 if the server includes
a Retry-After header in the response. This prevents duplicate side effects
for non-idempotent ExecuteStatement operations where the server has not
explicitly signaled that retry is safe.

The new opt-in parameter `_retry_server_directed_only` threads through
ClientContext, all three DatabricksRetryPolicy construction sites (Thrift,
SEA, UnifiedHttpClient), and the retry policy's should_retry/is_retry
methods. Default behavior (retry without requiring the header) is unchanged.

* Remove unnecessary _retry_server_directed_only instance variables

Inline kwargs.get() at the single point of use in ThriftDatabricksClient
and SeaHttpClient instead of storing as dead instance state.

* Address PR feedback: rename and clean up retry-after parameter

- Rename server_directed_only to respect_server_retry_after_header
  throughout for clarity
- Store _respect_server_retry_after_header as instance variable in
  Thrift/SEA backends to match existing kwargs extraction pattern
- Replace duplicate test fixture with _make_retry_policy(**overrides)
  helper for flexible policy construction in tests
